TANK-HEATER.

Specification of Letters Patent.

Patented Feb. M 1910.

Application filed April 12, 1909. Serial No. 489,432.

To all whom it may concern:

Be it known that I, Hum-1 Tmnna, a citizen of the United States,residing at Anamoose, in the county of Mellenry and State of NorthDakota, have invented a new and useful Improvement in Think-Heaters. ofwhich the following is a specification.

My invention is an improvement in tank heaters, and consists in certainnovel constructions and combinations of parts hereinafter described andclaimed.

The object of the invention is to provide a means for heating the waterin a tank or reservoir, the heater to be partially submerged in thewater, and having means for supplying fuel, and for permitting theremoval of ashes, and the entrance of sutficient airto properly consumethe fuel.

Referring to the drawings forming a part hereof, Figure 1 is aperspective view of the improvement. Fig. 2 is a longitudinal section,and Fig. is a horizontal section.

The present embodiment of the invention, comprises a casing 1,rectangular in cross section, and provided at its bottom with a lateral.flange 2, which may be secured to a base 3, by means of bolts l, thebase resting upon the bottom of the tank The casing is provided with anopen top having a lateral flange 6, and is closed by a cover 7 having aflange 8 fitting within the open top, and a handle 9, for convenience inmanipulating the same. At its lower end, and on one side the casing isprovided with an inlet pipe 10, also rectangular in cross section, andinclined with respect to the casing, the pipe being braced by means of abar 11 connected with the pipe and the casing. The inlet pipecommunicates with the casing near its bottom and is provided at its freeend with overlying flanges 12, which form guideways for a sliding door13, the door having its free edge beaded as at 14, to form a handle formoving the door.

A fire box 15 is arran ed within the cas ing, the box being providedwith a lateral flange 16 resting upon a ledge 17, secured to the innersurface of the casing by brackets 18. The lower edge of the fire box isslotted as at 19, for the entrance of air, and a grate 20 of circularform closes the bottom of the fire box, the grate being rotatable, on asupport 21, connected with the casing. The grate is provided with anextended lug 22, having an opening therethrough in which engages a ring23 on a rod 2 1, whose free end extends up the inlet pipe to a pointadjacent to the door 13 and is provided with a ring 2 1-, forconvenience in handling. By the proper lmnlipulation ot' the rod, thegrate may be oscillated to shake out ashes and the like, and when not inuse a hook 2o is provided on the inner surface of the pipe for engagingthe rod as shown in Fig. 2.

It will be understood that the grade divides the lower half of theeasing into the [ire box proper, and an ash chamber, with which theinlet pipe 10 communicates, and in the opposite wall from the opening ofthe inlet pipe, is provided an opening 27, and above the upper edge ofthe tire box, in the same wall, is another opening 28, both openingseom1nu nicating with a smoke chamber 2!). The smoke chamber is shown assemi-circular in cross section, and about midway between the openings27, and 28, a smoke stack or pipe 30, leads outwardly and then up 'ardlyfrom the smoke chamber. The opening 27 is provided upon each side with aguide way 31, and a damper 32 is slidablc in the guideways, the loweredge of the opening being provided with a stop 33, against which thelower edge of the damper rests, when in lowermost position. The upperedge of the damper is provided with a lag 34, having an openingtl'icrethrough, through which passes a rod 3.3,whose lower end is headedto prevent its passage through the opening of the lug, and whose upperend is provided with a ring 36, for convenience in handling, the rodtraversing a slot 37 in the cover. It will be evident that by openingthe damper more or less the draftthrough the fire box may be more orless diminished, while by closing the door 13 more or less the inlet ofair may also be regulated.

A hopper 38 is supported within the upper part of the casing, the upperedge of the hopper having an annular flange 39, engaged by brackets 10,on the inner face of the casing. A chute 41 extends from the lower endof the hopper to a point below the level of the upper edge of the tirebox. A diaphragm 12 is supported within the easing at the junction ofthe hopper with the chute by means of brackets 43, secured to the innerface of the casing, and the diaphragm shuts off the upper part of theeasing outside of the hopper from lower part.

In operation, the heater is placed in the tank or reservoir, and restingupon the bottom thereof, with the water line as shown by dotted lines in2. The fire is kindled within the fire box, the door 13 being open, andthe damper 32 being closed. Fuel is supplied through the hopper 38, thechute being normally closed by the fuel therein. The products ofcombustion pass upwardly around the chute and through the opening 28 tothe smoke chamber, and from thence to the stack. After the fire isburning well and the water sufliciently heated, the damper 32 is closedmore or less to reduce combustion, and retain the temperatureapproximately constant. The cinders and ashes may be removed from theash pit, by means of a suitable instrument introduced through the inletpipe 10, which is large enough and is inclined for this purpose, and thefire may be cleaned by shaking the grate, and may be started through thehopper. The smoke stack is braced to the casing by a brace 44E as shownin Figs. 1 and 2.

It will be observed that the flange of the fire box, the flange of thehopper, and the diaphragm which is secured to the chute rest upon thebrackets, and may be all removed from the casing, by lifting them outthrough the open top.

I claiml. A tank heater, comprising a casing having an open top, a coverfor the top, a fire box supported within the casing, a grate below thefire box, an inclined inlet pipe communicating with the casing below thegrate, a door for closing said pipe, a rod within the pipe and connectedwit-h the grate for shaking the same, the free end of the rod extendingto a point adjacent to the door, a smoke chamber on the opposite sidehopper and casing and closing the space be-' tween the outer wall of thechute and the inner wall of the casing.

2. A tank heater, comprisinga casing, a fire box within the casing, agrate below the fire box, an inlet pipe connnunicating with the casingbelow the grate and inclined to permit the-entrance of a tool, meansextending through said pipe for manipulating the grate, a smoke stack onthe opposite side from the inlet pipe, and opening into the caslng aboveand below the fire box, a clamper for the lower opening, means extendingoutside the casing for operating the damper, and a hopper delivering tothe fire box.

3. A tank heater, comprising a casing, a fire box within the casing, aninclined inlet pipe opening into the casing below the fire box, a smokestack communicating with the casing above and below the fire box, adamper controlling the lower communication, means for supplying fuel tothe fire box, and a door at the outer end of the inlet pip e.
